Here is a benchmark ripped from the Computer Language Shootout (http://shootout.alioth.debian.org). Running "binary_trees.py 18" takes the following time: -> without patch: 330s. -> with patch: 201s. (40% speedup) -> with GC disabled : 165s. Running pybench --with-gc doesn't show any performance variation, which seems to imply the overhead of the heuristic is negligible.
